To all whom 'it may concern:

Be it known that we, JOHN MoCnosKEY and HER'RiK J. GRAY, citizensof the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented certain newv and iuseful Improvements in Syrup-Dispensin A paratus, of which the following 1s a'fuih c ear, and exact description, `reference being had to the accompanying drawings, forming partof this specificatlon. y l' Our invention relates to a syrup dispensing apparatus having a pump fordrawing syrup from'jars =usedvat vsoda water fountains and the invention' {l1-as for its object to provide an apparatus'A having a pump construction in w iich the nozzle remains in a stationary osition when the pump is operated, there y avoiding liability of breakage of the tumblers held to receive the syrup discharged thereinto by the pump, as distinguished from other pumps made for like use in which the nozzle is a movable` member and has a rise andV fall motion during the operation of the pum plunger, and therefore moves down- War y to the tumbler held beneath it when the syru is being drawn.

A furt er objectof our invention is to provide an adjustment in the pump exterior of the syrup jar by which the degree of movement of the pump plunger may beA regulated withoutfthe necessity of removing the pump from the jar and without handling portions ofthe pump which are exposed to the syrup l.and are therefore disagreeable parts to handle without thoroughly removing the syrup therefrom.

A further object of our invention is -to construct parts of the pump which enter into the syrup of material which is unsusceptible to corrosion when in contact with the syrup and of such nature that it will not taint the syrup so as to cause the syrup to be'injurious in any way to the health of persons who partake ofl the syrup.

Figure I is a vertical section taken through a portion of a soda-water fountain counter, a

syrup jar therein and our pum shown in o erative position in said jar. ig. I is an e evation of fragments of the flanged pump supporting plate seated in the counter and the cap of the ump that is connected to said plate. Fig. I is a to or plan view of the parts shown in Fig. the counter bein partly broken away. Fig. III is a horizonta section taken on line 11i- 111, Fig. I.

IV is a vertical section taken on line IV -I Fig. I.

1 designates a counter which is preferabl cut out at the top to form a recess 2 at whic is located a pump supporting plate 3 having an upwardly extending flange 3. 4 is a jar horizontally arranged that is seated inthe counter'l and is provided with a well 5 located at its forward end and occupying a pocket 1a in the counter therebeneath.

6 designates a cup seated in the well of the` jar 4 and in which are radial orifices 4or o enin s 7 located at the top of the well in t e wal thereof where it projects above'the bottom of the jar so as to permit iiow of syrup from the main portion of the jar to said cup. The cup is preferably surroundedby packing 8, sol as to completely fill the space between the wall of the Well and the wall of the cu and securely hold the latter from being lifted by the suction of the lunger.

9 designates a cap t iat is mounted on the supporting plate 3 and provided with an inwardly projecting stud 10 (see Figs. I and Ia) adapter to enter a bayonet slot 3*.in the upwardly extending iiange 3 of the sup orting plate in order that the cap may be d ably held to said supportin plate.

11 designates the nozz e of my pump formed integral with the stationary head of the pump which is permanently seated on and sea/ted a nut 14.

15 is a discharge tube that is attached at its upper end to the nozzle 1'1 so that it has communication with the duct through said noz'- zle. The lower end of this discharge tube which is seater a nut 13 and Ain t e lower end of which is etachextends into the-cup 6 in the syrup jar in order that it may receive the syrup to conyduct it to said nozzle.

16 designates a plunger that is snugly fitted in the syru receiving cup 6 to operate therein and in w ich is an aperture through whichj screw thread engagement with the head of 4threaded upper end of the push stein beneath collar 20 fixed to said stem.

said stem. The )ush stein is located in the 'barrel and slidably {ittedin the nuts 13 and 14 in the-ends of the barrel and it is surrounded by a lift spring 19 that rests upon the lower nut 14 and is adapted to act against a The ush stein is provided at its u per .endwiti a screw thread 18 (see Fig.

21 is a'pusli knob that isl screw threaded l internally and fitted to the thread ofthe push stem, in order that it may .be adjusted on said stem.

22 is an adjustment nut that is fitted to the the ush knob and against which said push knob is adapted to bear. This adjustment nut serves to limit the downward thrust of the push stem and 'consequently of the plunger leconnected to the stem by the plunger rod,

theliniit'ation of movement being d ue to the abutting -of the adjustment nut against a stationary part of the pump head, for instance the nut 13 at the upper end of the barrel. and the adjustment nut may be readily and instantly adjusted to any desired degree so thatit will abut against the stationary part of the pump head upon either a greater or less degree of thrust of the stein to which it isa plied. Byregulatingthe degree of thrust oft e stem we/provide for a desired degree of movement of t e plunger 16 in the s up receiving cup 6 in order that any esirable amount of syrup may be discharged through the nozzle 11 when the plunger is moved downwardl in thel cup against the syru therein an( acts to force the -syru througii the discharge tube 5 and the nozz e 11 with which said discharge tube has communication. tsliould also be notedthat the adjustment nut 22 serves asa ain nut for the push knob 21. v A

The discharge tube 15 and the plunger 16 and its rod 17 of our pump are all constructed of hard rubber, a non-corrodible .substance and one which will not taint the syrup to be drawn through the medium of the pump and from which no injurious action upon the syrup can be transmitted ppint adjacent We .claim:-v 1. A syrup dispensing apparatus comprising a cup provi( n a lunger chamber, a.

pump supporting p ate aving an u wardly v extending flange, a cap ttin on the pump supporting plate, a pump hea having a nozzle and a i epending barrel and supported on the cap, u er and lower nuts secured to the upper and)l)ower ends of the barrel, respectively, a push stem having a collar and o erating in the barrel, alift spring sui'roumv ing the push stem between the' "lowerfnutfand the collar, a plunger rod connectedwithf'the'push stein, and provided with a plunger adapted to'operate 1n the cup, anda discharge tube leading from lthe cup to the nozzle.

3. A syrup dis ensing apparatus comprising a cup provi ing a plunger-chamber, a

extending flange, a cap fittiii on the pump supportin plate, a pump hea having a nozzle and a epending barrel and supported on the cap, u er and lower nuts secured to the upper an( ower end-sof the. barrel, respectively, a push stem having a collar and'operating in the barrel, a combined adjustment and jam-nut on theupper end fof the push stem, an adjustable push knob secured to the extremity of the push stem above the "coinbined adjustment and jam-nut, a lift s ring surrounding the push stem between the ower nut and the collar, a plunger rod connected with the ush stem, and rovided with a plunger ai apted to operate in the cup, and a disclarge tube leading from the cup Vto the nozz e.
